Application filed October 2, 1926. Serial No. 139,140;

" The present inventionrelates to a hopple for cultivators and has, foritsprime objectto provide an adjustable structure which may be used toadvantage also in scrap ng a cotton and 1n trashy ground.

Another'important object of the inven-- tion lies in the provision of adevice of this nature which is possessed of an exceedingly simplestructure and which maybe man- 10 ufactured at a low cost, one which 18strong and durable, easy to manipulate, thorougln ly reliable andefficient in use, and otherw se well adapted for the purpose for WlUCll1t is designed.

With the above and numerous other objects in view, as will appear as thedescription proceeds, the invention resides 1n certain novel features ofconstruction, and 111 the combination and arrangement of parts as Willbe hereinafter more fully described and claimed.

In the drawing: r

Figure 1 is a rear elevation of the device showing the same associatedwith a cultlvator,

Fig. 2 is a front elevation of the devlce.

Referring to the drawing in detail, it will be seen that 5 denotes oneside bar of the hopple having the upper end curved in- 30 wardly as at6. The numeral 7 denotes the other bar which is shorter in length thanthe bar 5 and has the curved upper end 8.

The terminals of the curved ends 6 and 8 are bolted together as at 9. Across bar 10 is bolted as at 11 to the bars 5 and 7 and is formed in twosections which overlap each other and have registering apertures 12 forreceiving bolts 14:. Thus the length of the cross bar 10 may beadjusted. An auxiliary bar 15 overlaps the lower end of the bar 7 and isbolted thereto as at 16 and 17 A stop 18 is bolted to the bar 7 as at 19be tween the bolts 16 and 17. On the bottom terminal of the bar 5 andthe auxiliary bar 15 there are pivoted pin plates 16 which are twistedat right angles between their ends. These pin plates are pivoted to thebar 5 and auxiliary bar 15 as at 17 and are adapted to be received inopenings 20 provided in the cross beams of the cultivator indicatedgenerally by the letter C in Fig. 1.

My improvement lies particularly in the joint 1617 provided between thebar 7 and the auxiliary bar 15. When the parts are disposed as is shownin the drawing, the device is used as an ordinary cultivator 'hopple.Then it is desired to use al ae,

vice in scraping cotton or in trashyground, the bolt 17 is removedandthen there is formed a hinged joint between thebar 7 and the bar 15which permits either plow beam of the cultivator to be raised until,

auxiliary bar 15 comes in contact with the left-hand end of member 18.This permits either plow beam to be shaken so as to swing the'plows orscrapers from any track and at the same time the plows are hoppled aswith any ordinary hopple.

It utility, and operation of this invention will now be clearlyunderstood by those skilled in this art without a more detaileddescription thereof. The present embodiment of the invention has beendisclosed in detail merely by way of an example, since in actualpractice it attains the features of advantage enumerated as desirable inthe statementof the invention and the above description. It will beapparent that changes in the details of construction may be resorted towithout departing from the spirit or the scope of the invention ashereinafter claimed or sacrificing any of its advantages.

Having thus described my invention what I claim as new is:

1. A cultivator hopple of the class described including, in combination,a relative- .ly long bar having its upper end curved, a relatively shortbar having its upper end curved, the extremities of the curves beingpivo-tally bolted together, an extensible cross bar between therelatively long and relative ly short bars, an auxiliary bar, a pair ofbolts attaching the auxiliary bar to the relatively short bar, one ofsaid bolts being removable to allow pivotal movement, a stop attached tothe relatively short bar between the bolts attaching the auxiliary barto the relatively short bar, and a pair of pin plates pivoted on theextremities of the relatively long bar and the auxiliary bar.

2. A cultivator hopple of the class described including, in combination,a relative- 1y long bar having its upper end curved, a relatively shortbar having its upper end curved, the extremities of the curves beingpivotally bolted together, an extensible cross bar between therelatively long and relatively short bars, an auxiliary bar, a pair ofbolts attaching the auxiliary bar to the relatively short bar, one ofsaid bolts being removable to allow pivotal movement, a stop is thoughtthat the construction,.

attached to the relatively short bar between the bolts attaching theauxiliary bar to the relatively short bar, and a pair of pin platespivoted on the extremities of the relatively long bar and the auxiliarybar, said pin plates being twisted intermediate their ends at rightangles.

3. A cultivator hopple of the class described including, in combination,a relatively long bar having its upper end curved, a relatively shortbar having its upper end curved, the extremities of the curves beingpivotally bolted together, an extensible cross bar between therelatively long and relativey ly short bars, an auxiliary bar, a pair ofbolts attaching the auxiliary bar to the rela the bolts attaching theauxiliary bar'to the relatively short bar, and a pair of pin platespivoted on the extremities of the relatively long bar and the auxiliarybar, said pin plates being twisted intermediate their ends at rightangles, the brace between the relatively short and long bars beingadjustable and being formed in sections bolted together.

In testimony whereof I aflix my signature.

LOUIS C. SUMMERS.
